Effects of Environmental Variations on Yield of Oriental Tobaccos

Abstract

The study was conducted to determine the impacts of environmental variations on yield and yield related properties of tobacco. The experimental layout was in the randomized blockswiththreereplicatesinfour differentlocations(Erbaa-Evciler,Erbaa-Karayaka, Gümüşhacıköy, Bafra) using 21 lines and four standard varieties that stand out with their different characteristics. The variation in plant height, number of leaves, leaf width, leaf length and leaf yieldof genotypes were investigated at different ecologies. All the parameters investigated of the genotypes have been significantly affected by changing environmental conditions. Plant height ranged from 49.33 cm to 177.32 cm, the number of leaves from 21.83 to 47.10 per plant, leaf width from 6.83 to 16.31 cm, leaf length from 13.01 to 28.93 cm, and yield ranged from 79.17 kg-1to 238.98 kg da-1. The results for the performances of genotypes in all environments showed that 5 lines (ERB-11, ERB-14, ERB-16, ERB-21, ERB-35) for plant height, 6 lines (ERB-6, ERB-7, ERB-11, ERB-14, ERB-16, ERB-35) for the number of leaves, 10 lines (ERB-9, ERB-16, ERB-17, ERB-18, ERB-19, ERB-21, ERB-25, ERB-26, ERB-27, ERB-30) for leaf width, 1 line (ERB-16) in for leaf length and 13 lines (ERB-6, ERB-7, ERB-9, ERB-13, ERB-16, ERB-18, ERB-19, ERB-21, ERB-25, ERB-27, ERB-30, ERB-35, ERB-38) for yield come to the fore.
